Each is bottoms in the hole in which it is fitted to the adapted to be driven from a continuously-rocasing. The pin d also serves to limit the 8o tating wheel l2 through' a clutch 13, which movement of the oil-receiverin one direction. serves to engage its shaft with the wheel 12 Registering with the ports b2 and b3 when when the shaft is rotating or to disengage it the oil-receiver B is in its normal position 35 therefrom when the shaft is stopped. It is are the duct a2, leading to the bearings of the therefore necessary to maintain the lubricaupper shaft 9, and the duct or pipe C, leading tion of the wheel l2 when rotating on the to the bearings of the lower shaft. In the stopped shaft, as well as of the clutch 13, that machine illustrated the pipe C, which leads the latter may slide freely on the shaft. For from the reservoir to the lower shaft, is of 4o clearness the wheel 1.2 and the clutch 13 are such greater volume than the ducts leading not shown in place on the lower shaft 25, and to the upper shaft that means must obviously 9o the devices for effecting the engagement and be provided to prevent the delivery to the disengagement of the clutch and its wheel pipe C of all the oil introduced into the oilhave been entirely omitted, as they are not receiverB. If this should occur, one bearing 45 material to my invention. In the machine would have for reserve lubrication all the oil illustrated its frame constitutes a part of the retained in the pipe C and its connections, reservoir, being appropriately formed to serve while the' other shaft would have only the inas a casing therefor. The portion A of the adequate quantity retained in the short duct frame A immediately above the upper shaft 0.2 and its connections. To meet this condition, the oil-receiver B is made with chambers of different volumes, the smaller of which communicate with the longer ducts and connections. 'lhe outlets from these chambers are at different levels, so when the oil has ceased to dow to the larger set of ducts there still remains a sufficient quantityin the reservoir to supply the other ducts for an extended period. The shafts are both formed with axial bores, from which lead radial ports 9 and 25, so located as to intermittently register during the rotation of the shafts with the openings of the ducts a2 and of the pipe C. The oil is thus admitted to the central bores ot' the shafts, through which it is distributed to the different bearings. Radial ducts lead from the central bore of each shaft to the shaft-bearings and to the bearings of the clutch 13 and of the clutch-wheel 12 on the shafts, through which oil is forced by centrifugal action. As the radial ports in the shafts are not in continuous comtnunication with their ducts, but register therewith only intermittently, the appropriate quantity of oil is fed to the bearings to maintain lubrication without excess or waste. The opening of the bore at the end of each shaft is closed by suitable means, in this instan ce bya screwplug 19, whose head serves to retain the clutchwheel 12 in place on its shaft.

The reservoir is filled by sliding the oil-receiver B into the position indicated by the dotted lines in Fig. 2, where it closes the openings to the oil-ducts a2 and C. When filled, the oil-receiver is returned by the spring e to its normal posit-ion, thus opening the oil-ducts and permitting the oil to l'low to the various bearings.

Unless some means be provided for gaging the amount of oil introduced into the reservoir waste both of time and of oil as well would occur and there will result lack of uniformity in the amount of oil introduced. The amount of oil that may be contained in the oil-reservoir B is ample to supply the machine-bearings for an indefinite period, and therefore, serves as a gage or measure of the quantity of oil to be employed. The machine attendant has but one thing t0 remember when oiling the machine-to open the receiver and till it. That is all. IIe need exercise no judgment as to the number of drops to be applied to different bearings. There is but one point at which to introduce oil, and at this point the only precaution to be exercised is to till the receptacle provided.

Myinvention is described as applied to a certain type of machine and to a certain arrangement and relation of bearings; but it is obviously not limited to the precise manner of application described. The oil-reservoir is susceptible of application to single bearings as well as to a plurality of bearings. The casing for the reservoir need not be formed in av machine-frame, but may be entirely separate therefrom, to be attached by any suitable means.

Without limiting myself to the precise form of structure described, I claiml. The combination with a plurality of shafts having axial chambers and radial ports, and shaft-bearings, of a single oil-reservoir above said bearings, and duc t s leading from the reservoir to such shafts, and means for automatically supplying oil in graduated quantities to said ducts substantially as described.

2. In a lubricating device, the combination with a plurality of shafts having axial bores therein and radial outlets therefrom to the bearings of the shafts, of a single oil-reservoir to receive oil for distribution to the different bearings, having ports through which the oil is discharged, and ducts that distribute the oil from said ports tothe various shafts, and means whereby the reservoir-ports are closed by opening the reservoir for theintroduction of oil, andopened by the closing of the said reservoir, substantially as described.

3. In an oiling device, an oil-reservoir with an oil-receiver movable therein, having an inlet normally covered by the casing of the reservoir, and arranged to be uncovered by moving said receiver, and outlet-ports arranged to be opened when the inlet is closed, and to be closed when the inlet is opened, shafts having axial chambers with ports communicating with the various shaft-bearings and having also inlet-ports to receive the oil from the reservoir, and ducts leading from the reservoir-ports to lthe supply-ports of the different shafts, substantially as described.

4. The combination with a plurality of shafts having bearings in a machine-frame A, of an oil-reservoir located above said bearings, ducts leading from the reservoir to the bearings, means for opening the reservoir for the introduction of oil and whereby the ducts are at the same time closed, and means for automatically closing the reservoir to the introduction of oil and opening the oil-ducts, substantially in the manner described.

5. In an oil-reservoir, a casing A' havinga XOO bore a and ducts leading therefrom, an oil-receiver B movably mounted in said bore, having an inlet for the reception of oil and outlet-ports registering with the ducts, substantially as described.

6. In an oil-reservoir, a casing, an oil-receiver movable in the casing having chambers of different volume, and ducts leading from the various chambers, in the manner and for the purpose substantially as described.

'7. In an oil-reservoir, a casing, an oil-receiver longitudinally movable in the casing having an inlet for the introduction of oil, and chambers of different volume, ducts leading from the reservoir to different bearings, the casing having ports to connect the chambers with the ducts, adapted to be closed While the inlet is open to fill the reservoir, and open when the inlet is closed, in the manner and for the purpose substantially as described.

8. In an oiling device, the combination With a reservoir, Yof a movable oil-receiver forming part of the reservoir, oil-ducts leading from .the reservoir 'ro bearings, outletports in the oil-receiver to register with the ducts, and an inlet to the receiver for the introduction of oil, substantially as described.

9. In an oil-reservoir, casing A having a bore a and ducts leading therefrom, an oilreceiver movably mounted in said casing having an aperture for' the introduction of oil, and outlet-ports through which the oil is delivered to the bearings, and means to insure the alinement of the ports with the ducts, substantially* as described.

l0. In an oil-reservoir, a casing A', a cylindrical oil-receiver B adapted to be moved longitudinally in the casing and having an elongated opening b and outlet-ports h2 and b3, a pin d entering said elongated opening to prevent the rotation of the receiver B, a spring e between the end of the receiver and the pin d to move the receiver Bin its casing, and a capf to close the end of the receiver and limit its movement under the action of the spring e, substantially as described.

ll. In an oil-reservoir, a casing, an oil-receiver movable in the casing having an inlet for the introduction of oil and outlet-ports to deliver the oil from the reservoir, so locatedA that when the receiver is moved to open the inlet, the outletports are closed, and when the inlet-portis closed, the outlet-ports are open, substantially as described.

12. The combination with the bearings of one or more rotary shafts, of a cylindrical oilreceiver adapted to slide longitudinally in a casing above the shafts, having ports adapted to normally register with oil-ducts leading to the bearings of the shafts, an elongated inlet in the top of said receiver, means whereby pressure on one end of the receiver will force the latter longitudinally in its bearing to close the ports and expose the inlet, a pin projecting from the casing into the inlet to prevent the rotation of the receiver and adapted to engage the end of the inlet to limit the movement of the receiver in one direction, a spring between the pin and the end of the receiver to return the latter to its normal position to close the inlet and open the ports, and a cap to close the end of the receiver and limit its movemeut under the action of the spring, substantially as described.
